Drying method for engineering plastics
As the process moisture increases, the shear viscosity of the material decreases. The change in flow properties during processing is reflected in a range of process parameters and the quality of the products produced. The general effect of excessive process moisture is over-pressure or foaming. Other defects that are caused by improper drying include yellowing of the material caused by water marks or excessive stagnant time. If the residual moisture content is too low and the viscosity increases because the stagnant time is too long, this may cause problems similar to insufficient filling. The main problems caused by the change in performance are not directly visible to the product, but can only be discovered by proper testing of the components, such as mechanical properties and dielectric strength.
